1.在AndroidManifest.xml中加上两个权限：<uses-permission android:name="com.sec.android.provider.badge.permission.READ" /><uses-permission android:name="com.sec.android.provider.badge.permission.WRITE" />2.查看你的APP是否已经注册在BadgeProvider中：Uri uri = Uri.parse("content://com.sec.badge/apps");Cursor c = getContentResolver().query(uri, null, null, null, null);if (c == null) {    return;}try {    if (!c.moveToFirst()) {        return;    }    c.moveToPosition(-1);    while (c.moveToNext()) {        String pkg = c.getString(1);        String clazz = c.getString(2);        int badgeCount = c.getInt(3);        Log.d("BadgeTest", "package: " + pkg + ", class: " + clazz + ", count: " + String.valueOf(cnt));    }} finally {    c.close();}3.如果没有注册就注册上去：ContentValues cv = new ContentValues();cv.put("package", getPackageName());// Name of your activity declared in the manifest as android.intent.action.MAIN.// Must be fully qualified name as shown belowcv.put("class", "com.example.badge.activity.Test");cv.put("badgecount", 1); // integer count you want to display// Execute insertgetContentResolver().insert(Uri.parse("content://com.sec.badge/apps"), cv);4.如果已经注册了就用下面方法更新角标：ContentValues cv = new ContentValues();cv.put("badgecount", 0);getContentResolver().update(Uri.parse("content://com.sec.badge/apps"), cv, "package=?", new String[] {getPackageName()});附：BadgeProvider　https://github.com/shafty023/SamsungBadger
